Sue Frownfelter, a 46-year-old mom in Flint, Michigan, thinks it's less of an issue for parents who discover technology with -- or even before -- their children. Among other things, she has a blog, uses Twitter and has a Chumby, a personal Internet device that displays anything from news and weather to photos and eBay auctions.

Her children, ages 9 and 11, begged her to allow them to have a MySpace page, because she does. Instead, she suggested Imbee.com, a social networking site for kids that allows parental monitoring.

I hadn't heard of Imbee yet. I finally just joined Facebook, and have pledged to myself to do better at keeping up with technology, for the very reason cited above.
